A police officer is dead after a fiery crash on I-64 reportedly involving a semi and an LMPD cruiser.

Officials identified the deceased as LMPD Det. Deidre Mengedoht, 32. Police chief Steve Conrad said Mengedoht had served seven-plus years with the force.

Mengedoht was reportedly conducting a traffic stop on a truck with four passengers inside when an MSD truck crashed into her cruiser. The officer's cruiser then struck the truck that had pulled over and caught fire. Investigators said the officer had her emergency lights on and was in the right-hand lane.

Louisville's police chief is launching an investigation into the arrest of a man left swollen and in a neck brace after an altercation with an officer with the Louisville Metro Police Department Sunday afternoon.

After reviewing body camera footage, LMPD Police Chief Steve Conrad has launched an investigation led by LMPD's Professional Standards Unit. The investigation will attempt to determine if any departmental policies were violated.

Greg Fischer and Angela Leet both live and work in Louisville, but the two painted drastically different pictures of the city in their second and final debate Tuesday night, three weeks out from Election Day.

Fischer, the incumbent Democrat seeking a third four-year term, pledged in his closing remarks to build on the successes of his tenure, highlighting accomplishments in his description of Louisville's "renaissance."

The Rev. Kevin Cosby doesn't believe he's above the law. But he does want consistency in its enforcement.

"I am entitled, like all people in West Louisville and in urban communities, to equal protection under the law," Cosby told University of Louisville professor Ricky Jones in a recorded interview. "I just want consistency."

A Jefferson Circuit Court judge has denied Louisville Metro Police Lieutenant Jimmy Harper's request to be reinstated to his position as major, in part because of the hostility between Harper and Chief Steve Conrad.

A jury trial earlier this month ended with Harper winning a $300,000 verdict. He sued claiming he was demoted from the rank of major in retaliation for speaking out to Mayor Greg Fischer about how the department was being managed by Conrad.

Attorneys for the city have accused Metro Council President David James of "acting in collusion" with a Louisville police officer who has filed a whistleblower lawsuit against the department and Metro Government.

Louisville Metro Police was tight-lipped Thursday afternoon hours after Chief Steve Conrad said a man was shot and killed by an officer in the Southside neighborhood.

Conrad said officers were sent to the Colonial Oaks apartments near Colonial Oaks Court and Southside Drive just after noon on Thursday. Dispatchers received several calls about a domestic violence disturbance that was taking place there.
